Instrumentation and Control Systems

Overview

[Development and design]

We draw up basic designs for instrumentation and control systems which uses general-purpose PLCs and proprietary control systems supplied by Yokogawa Electric, Azbil, TMEIC, and other industrial instrumentation manufacturers. In addition, we create detailed designs for the hardware and software incorporated into those systems. We also have an in-house development environment for differential scanning calorimeters (DSCs) and general-purpose PLCs.

[Production and installation]

In our development environment, we incorporate an instrumentation and control system, including control panels and operator desks, and perform an integration test of its hardware and software components. After installing the system in a customer’s facility, we test-run it by starting it up, performing loop tests, and adjusting the proportional-integral (PI) control.

Electrical Control Systems

Overview

[Development and design]

Based on the wealth of technical expertise, we have accumulated for years in installing and refreshing electrical control systems at steel plants, we build high-performance and reasonably priced electrical control systems which meet the requirements of customers and operational processes by using general-purpose programmable logic controllers (PLCs), such as Mitsubishi MELSEC and Fuji MICREX-SX, open networks, and AC/DC drive systems.

[Production and installation]

We design and produce to customers’ specifications master control panels, inverter panels, hydraulic pressure control panels, operation panels, and other control panels as well as PLC software. Then we conduct an internal test using using our stringent quality-control procedures so that we can go on to install and test-run the systems in customers’ facilities within a compressed timeframe.

[Maintenance]

Using general-purpose PLCs and inverters instead of proprietary equipment supplied by heavy-machinery manufacturers enables us to obtain a replacement for failed equipment faster and for less, resulting in a shorter downtime for the system. Another benefit of using general-purpose equipment is that the system can be modified at lower cost.

Electrical Works

Overview

[Installation]

Commercial buildings and public facilities such as educational facilities, medical facilities, logistic facilities and transportation services must have fully functional electrical, air-conditioning, information and communication, and fire-fighting systems to enable people work and receive services in a safe, comfortable environment. Drawing on our extensive experience and solid track record as well as our engineering prowess, we install high-quality infrastructure systems in customers’ facilities to create a safe, comfortable environment.

[Maintenance]

We provide maintenance services for power receiving and distributing equipment installed in buildings and facilities.

Piping Works

Overview

JFE Planteng performs engineering of the design, fabrication, and installation of piping for all applications, as well as related support structures, using the “Design database” and “Piping/stanchion, etc. strength evaluation technology” developed by this company.

Installation Works of Steel Structure

Overview

The Kurashiki Machining Section is located in the Mizushima Industrial Complex, which faces Japan’s Seto Inland Sea.
With the Boiler Shop and Machine Shop located in adjoining buildings, this is an coastal works with an integrated processes for assembly, welding, and machining of large-scale steel structures, including shipment of the finished product.
Technically, this plant boasts an accumulation of welding and machining technologies for production of high accuracy large-scale steel structures, and has also created a large number of produ

Photovoltaic Power Systems

Overview

[Design]

We design solar power system capable of generating electricity at a rate of anywhere from 100 kW to over10 MW. Before starting design work, we inspect the site where a system is to be installed—rooftop of a building, level ground, hilly area, or in a lake. Based on the findings of this on-site investigation of a building’s structure, underground stability, depth of the lake, and the solidness of the lakebed, we create an installation map. Then we select from various options the panels and mounting systems that best meets the customer’s needs and budget.

[Installation]

We have installed a large number of solar systems with a combined power-generating capacity of more than 200 MW to date, including quite a few megawatt solar farms.
